is spindle speed . Unit: rev/min
When the converter spindle is controlled by S function, and the corresponding highest speed with
the output 10VDC is defined by P09, P10, P23 and the spindle gear control signal M41, M42,
M43.
When M41
（
low gear
）
is valid
，
the voltage to which the spindle speed corresponds is defined by
P09
；
When M42
（
medium gear
）
is valid
，
the voltage to which the spindle speed corresponds is
defined by P23
；
When M41
（
high gear
）
is valid
，
the voltage to which the spindle speed corresponds is defined by
P10
；
When the system is turned on, it defaults M43, i.e. the high spindle speed.
3.4 T Function — Tool Function
Usually, it is necessary to have different tools to machine a workpiece. The rotation tool post with
4
～
8 tool selections can be controlled by the system( the signal of 1
～
4 tool selections can be
directly input and 5
～
8 ones can be input by code signal). To avoid the error caused by the
installation or the wear and tear, each tool is placed in the different position when it is cutting the
workpiece, the tool change and the tool compensation are employed in the programming.
Command format
：
T a b
a
indicates the tool range: when a is 0, the tool compensation is not executed. It
corresponds the four tools on the tool post with 4 four tool selections.(when the tool
post has six or eight tool selections, it is No.
１ —6 or No. １ —8 tool) ；
b
indicates the number of tool compensation data. 1
－
8 corresponds the group No. of
eight groups tool offset in offset parameters. （ No. 9 tool offset means X, Z coordinates
of returning to the machine home.
）
The most 8 tools and 8 groups offset value can be selected by the system. Usually the tool offset
No. is only used for the tool No. with the same tool offset No. , such as T11, T22, T33, T44, T55,
T66, T77, T88, which can gain the correct offset when the tool change is executed. For a special
compensation or a micro tune of some tool, the tool number cannot be the same as the tool offset
number.
When executing the fixed point toolsetting, the tool offset data which tool offset number is not
more than the tool amount can generate automatically and other offset data must be input by
keyboard (because it has not the corresponding tool number). When executing the trial cut
toolsetting, it is not limited because the offset No. can be input by keyboard.
In T command, b=0: cancel the tool offset compensation.
IF the tool offset is valid, the tool offset can be cancelled by returning to the starting point of the
program or executing G26, G27, G29.
When the line-up tool post are used, P11 Bit5 is set to 1 and the tool change key is pressed to
directly set the tool number as the new one without outputting the rotation signal to execute the
toolsetting according to the trial cutting or the fixed point toolsetting, which automatically
generate the tool offset.
